An inverter control for an N phase inverter includes a single memory which stores a plurality of bytes, circuitry coupled to the memory for developing a series of memory addresses for each phase output of the inverter, each series of memory addresses defining a phase output waveform to be produced and circuitry coupled to the developing circuitry for accessing the memory with a memory address from each series thereof during each of a number of accessing cycles so that N bytes are provided at an output of the memory during each accessing cycle. A demultiplexer is coupled to the memory for deriving gating signals for switches in the inverter from the bytes provided at the output of the memory.
